Local amplification of deep mining induced vibrations

Impact of deep mining vibration on surface constructions – Numerical approach. This paper investigates numerically the propagation and amplification of mine induced vibrations in coal basins. It consists in a general study for various basin geometries (canonical basins) and detailed analyses for the Gardanne coal basin (Provence, France).

The discharge of dewatering plumes, the analysis of the effect of vortex-induced vibrations (VIV) on mining risers, and the development of updated and detailed economic models -which are among the most pressing ones - are addressed in this thesis. PLUMEX field studies were conducted in the Pacific Ocean to create and monitor six dewatering plumes.

Deep-sea mining | IUCN

• Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.

Monitoring of TBM-induced ground vibrations

For the study on the propagation–attenuation rule of the blasting vibration wave in the deep mining roadway of Shizishan copper mine, and the analysis of the influences of different maximum explosive charges and different underground systems on the propagation of blasting vibration signals, blasting vibration monitoring of the two different situations has been carried out respectively.

Drilling - Wikipedia

This last technology is a fully industrial one (example: SineHoling® technology of MITIS). Vibration drilling is a preferred solution in situations like deep hole drilling, multi-material stack drilling (aeronautics) and dry drilling (without lubrication). Generally it provides improved reliability and greater control of the drilling operation.
